Though i don't care about GOTY, i would say Half Life Alyx based on its extremely positive critic and user reviews. Its also innovative. Majority of the games on this list are not innovative and have mixed reviews between critic and users.
However i think Animal Crossing will take the cake based on the fact it was a game that released at the perfect time in one of the worlds modern worst periods. It was a perfect escape from the real world, it truly deserves it on that front alone.
